Every human's greatest fear is that we are not enough and as a result that we won't be loved. We are born this way. It is human psychology 101. Without love a human baby dies. Other animals won't. So this is not some artificial construct that develops over time--it is hardwired into us at our most fundamental level, via our autonomic nervous system.
This swapping back and forth between the horrific and the mundane or even jolly, is not uncharacteristic of common ways of ways coping with chronic trauma: the black humour of a doctors' mess, for example.

And the visual illusion created by cut and fabric dramatically changes the appearance of your body. Your clothes can affect your job prospects, your love life and even your self-image.
The internet turned out to be the most democratic space which can be accessed by everyone who can use a bit of tech to better their lives and knowledge base...

But that is jumping the gun on policy, and may just further embed the status quo into our management of mental health problems.
I wouldn't hide behind a tree or a parked car to follow my ex-girlfriends every move? Nor would I invite every person I meet in a nightclub, to view my daughter's baby pictures. I don't stroll casually down the street screaming at the top of my lungs 'Well done me!' in regards to my personal achievements as I have no desire to be considered conceited or narcissistic.
